Abstract
The utility model discloses an energy-saving star-shaped circular wire diameter-expanded wire comprising an outermost aluminum wire layer, a middle star-shaped wire layer, and an innermost steel core. The steel core is formed by multiple steel wires. The star-shaped wire layer is formed by twisting multiple star-shaped wires. The aluminum wire layer is formed by multiple circular aluminum wires wrapped round the star-shaped wire layer along the radial direction of the star-shaped wires in a circumferential manner. The inner layer of the energy-saving star-shaped circular wire diameter-expanded wire is a star-shaped wire but not a pumping type. The energy-saving star-shaped circular wire diameter-expanded wire has stable supporting structure and good diameter expanding effect and reduces the cross section of the aluminum wires while guaranteeing wire outer diameter required by corona. Therefore, the energy-saving star-shaped circular wire diameter-expanded wire has advantages of reducing wire amount, reducing structural weight, reducing pole load, and substantially reducing line cost.
Description
Technical field
The utility model relates to a kind of energy-conservation star circle line expanded conductor.
Background technology
Global electric power transfer all is based on overhead transmission line, and aerial condutor is by the single cord of electric current or the twisted wire formed of the multi cord of mutually insulated not, is the necessary carrier from electric energy generating end to receiving end.China's overhead transmission line is based on steel reinforced aluminium conductor (ACSR), and its applicating history is above 100 years in the world.Traditional steel reinforced aluminium conductor transmission line capability be restricted and line loss bigger, explore new lead line style, efficient electric energy transmitting is various countries electric power scientific worker's continuous pursuit.
Transmission line adopts ultra high voltage, superhigh pressure to become the development trend that electric power is carried at a distance at present.Along with the lifting of electric pressure, aspect electric property, need consider corona characteristic and the resistance characteristic problem of lead.Corona is that electric potential gradient surpasses the free a kind of electric discharge phenomena that cause of lead ambient air after certain critical value.The operation of ultra high voltage, extra high voltage network is easy to generate corona, not only consumes a large amount of energy, and derivative radio interference and audible noise have a strong impact on biological environment.The general external diameter and the smooth finish surface that increase lead of adopting solves in the world.
The utility model content
The utility model purpose is to provide a kind of energy-conservation star circle line expanded conductor at the defective that prior art exists.
The utility model for achieving the above object, adopt following technical scheme: a kind of energy-conservation star circle line expanded conductor, comprise outermost aluminum steel layer, the astroid layer in intermediate layer and the steel core of nexine, described steel core is made of many steel wires, described astroid layer is by many stranded the forming of astroid, and described aluminum steel layer radially is circle-shaped encirclement by the aluminum steel of many circles along described astroid and is arranged in astroid layer outside and constitutes.
Preferably, described aluminum steel layer, astroid layer and steel core concentric-ring pattern are stranded.
Preferably, described aluminum steel layer is 1 layer, and the arbitrary adjacent layer strand of described energy-conservation star circle line expanded conductor is on the contrary, and outermost layer twists to being dextrad.
Preferably, described astroid layer also is provided with the clearance layer of 1-3 layer, and the clearance layer strand between adjacent is on the contrary.
The beneficial effects of the utility model: energy-conservation star circle line expanded conductor outermost layer aluminum steel of the present utility model is circular, internal layer is astroid, the non-strand type of taking out, supporting construction is stable, and hole enlargement is effective, guaranteeing under the desired wire diameter situation of corona, reduce the aluminum conductor cross section, thereby reduce the lead total amount, reduce construction weight, reduce tower bar load, reduce advantages such as circuit cost greatly.
